thehousehasbeenemptyformanyyears 3 表示将来 用于时间 条件等从句中 e g 我一完成工作就和你一起去 i llgowithyouassoonasihavefinishedmywork 注意 终止性动词一般不与延续性时间状语连用 所以有些句子在汉语中成立 在英语中则要适当变通 如 他参军已经三年了 不能翻译成 hehasjoinedthearmyforthreeyears 但可变通为 hehasbeenasoldier inthearmyforthreeyears hejoinedthearmythreeyearsago 但是终止性动词的否定式则可以用于完成时 如 wehaven tseeneachotherforalongtime 在 thisisthefirst second timethat
